DSMC MODELING OF VIBRATIONAL AND CHEMICAL-KINETICS FOR A REACTING GAS-MIXTURE

A zero-dimensional Direct Simulation Monte Carlo (DSMC) model is devel oped for simulating reacting gas mixtures including state-to-state vib rational kinetics and simple bimolecular reactions. The method is appl ied to the simulation of three systems: translational relaxation of a hard sphere gas, vibrational relaxation of an anharmonic oscillator ga s and dissociation in a simplified H-2-Xe system. In this last case, t he role of translational non-equilibrium is shown to be important in a ffecting the dissociation kinetics. (C) 1998 Published by Elsevier Sci ence B.V. All rights reserved.
